Often in data-science or machine learning hackathons, you may want to concatenate the rows of the train and test datasets for easy data exploration and wrangling. And when you want to do that, this pro-tip comes handy.Check the Pandas Documentation for more on this API.

It is so common a situation in data-science to select a subset of columns from a data-set. In Python the usual approach is to select a set of columns using List Comprehension or using pandas df.drop() method.I typically employ using the List Comprehension method of choosing a subset of columns. The drawback of this approach is that it is verbose over its drop() counterpart. However, there is a distinct advantage with this approach which is that this approach guarantees idempotency.Being a huge fanboy of idempotency coming from a mathematical background and a hatred for verbosity and duplication, I came end-up using the utility methods shown in this blog post. Clearly, this utility function gives the advantage of brevity and idempotency. Yay, I win!

This was a decade when it was not easy for a start-up to even give birth, for things were so complex and expensive too. There wasn't promulgation of open-source tools and technologies and the cheap cloud that takes so much of the pain out from you for infrastructure management was simply not there. This was an era when one enterprise was painfully dependent on other for the specialized services that the other provides. This mandated the need for Project Managers over Engineering Managers. And the viral joke in the community was something like,

"If you got a person in the development team who is not capable of any of its function but is surviving by his glib talk, make him a Project Manager".
